Generic Allopurinol Buyer and Patient Handbook in Singapore
What is Allopurinol?
Allopurinol is an oral medication classified as a xanthine oxidase inhibitor used to lower uric acid levels in the body. It is primarily prescribed for Gout, chronic Hyperuricemia, and prevention of uric acid Kidney Stones. The drug is approved by the Health Sciences Authority (HSA) in Singapore and is available as a 300 mg tablet.
Who Should Use Allopurinol?
- Adults diagnosed with gout or recurrent hyperuricemia.
- Individuals who have formed uric acid kidney stones.
- Patients whose uric acid levels remain high despite dietary measures.
How Does It Work?
Allopurinol blocks the enzyme xanthine oxidase, which is responsible for converting purines into uric acid. By reducing uric acid production, it helps prevent crystal formation in joints and kidneys. The medication does not relieve acute gout pain; it works as a long-term preventive therapy.
Why Choose Allopurinol?
- Proven efficacy: Widely studied with consistent uric-lowering results.
- Once-daily dosing: Improves adherence compared with multiple-dose regimens.
- Cost-effective: Generic version offers substantial savings over brand-name alternatives.
Dosage, Administration, Lifestyle and Dietary Recommendations
Recommended Dosage
- The typical maintenance dose is 300 mg once daily, taken as a whole tablet.
How to Take
- Swallow the tablet whole with a full glass of water.
- It can be taken with or without food; consistency helps maintain stable blood levels.
Missed Dose
- If you remember within 12 hours, take the missed tablet.
- If it is near the next scheduled dose, skip the missed one and continue as usual.
Overdose
- Seek immediate medical attention if you suspect an overdose.
- Common signs include severe Nausea, Vomiting, or dizziness.
Special Populations
- Elderly: Start at a lower dose (100 mg daily) and titrate cautiously.
- Renal impairment: Dose reduction is required; consult your healthcare provider for individualized dosing.
- Pregnancy & breastfeeding: Use only if clearly needed; discuss risks with a clinician.
Lifestyle & Diet
- Maintain adequate hydration (≥2 L water daily) to aid uric acid excretion.
- Limit high-purine foods such as organ meats, anchovies, and shellfish.
- Avoid excessive alcohol, especially beer, which can raise uric acid levels.
Precautions and Warnings
- Test for hypersensitivity before starting; severe skin reactions, though rare, can be life-threatening.
- Monitor liver and kidney function regularly during therapy.
- Do not combine with high-dose aspirin or Azathioprine without medical supervision.
Drug Interactions
| Drug Class / Example | Interaction Risk | Recommended Action |
|---|---|---|
| Thiazide diuretics | ↑ uric acid, reduced efficacy | Monitor uric acid; adjust dose |
| Azathioprine | ↑ toxicity (bone marrow) | Reduce azathioprine dose or avoid |
| Warfarin | ↑ INR | Check INR more frequently |

Reviews
Started two weeks ago for gout. The first few days were rough, felt super tired and had a weird rash on my arms. Doc said it's normal, so sticking with it. Hoping the joint pain goes away soon, it's brutal. Taking it right after breakfast seems to help with the nausea.
Been on 300mg for 6 months now. Zero gout attacks, which is amazing. But the trade-off is serious dry mouth, especially at night. I keep a water bottle by the bed. Also learned the hard way: don't skip a dose, the rebound isn't worth it.
My uric acid levels are finally normal after a year. But it messed with my liver enzymes a bit, so now I get extra blood tests. Doctor says it's manageable. I take it with my biggest meal to avoid stomach upset. Small price to pay for no more crippling pain.
It stopped the gout flares, but now I get these weird tingling sensations in my feet sometimes. Not painful, just annoying. Doctor says it's a rare side effect. Still debating if it's better than the alternative. I split my pill and take half in the morning, half at night, seems to lessen it.
Life-saver for my kidneys. Been on it 3 years for high uric acid due to CKD. No issues, but you HAVE to drink a ton of water. Like, 3 liters a day minimum. If I get lazy with water, I feel fatigued. It's a discipline thing now.
Works great, but the initial flare-up when you start is no joke. Felt like my big toe was going to explode. Doc gave me colchicine to get through it. Pro tip: start on a lower dose if you can, 100mg, and work your way up. Much easier on the system.
I take it for gout, but it's given me really dry eyes. Use eye drops constantly now. Weird trade-off. Still, being able to walk normally is worth it. I take it right before bed, seems to reduce the drowsiness during the day.
After 8 months, I can finally eat some seafood without a panic attack. But I have to be super consistent. If I take it even a few hours late, I can feel a twinge in my joints. Set a phone alarm. It's not a magic pill, you still gotta be careful with diet.
